The family members, dressed in casual attire, smiled brightly together. They were joined by their two adopted pet dogs.

William and Kate first met at Scotland's St Andrews University in the early 2000s. They married at Westminster Abbey in London on 29/4/2011, an event watched by millions. Public interest in the couple has remained high since their wedding.

During their 15 years of marriage, William and Kate welcomed Prince George in 2013, Princess Charlotte in 2015, and Prince Louis in 2018. The couple also supported each other as Princess Kate battled cancer.

Last year, for their 14th wedding anniversary, William and Kate undertook a two-day visit to the Mull and Iona islands in Scotland.
